s claims. (ci. 19-159) This invention relates to drawing frames and other similar machines, and more particularly to mechanism provided for continuously moving `the sliver cans during the operation of the machine and as' the product of the machine is being coiled therein. A

It is desirable that the sliver be deposited in superposed but circumferentially displaced coils in the sliver cans, and it ,is also desirable that no twist be imparted to the sliver by the motion of the can.

It is the general object of my invention to provide improved and very simple mechanism for producing a circular but non-rotational motion of a sliver can in a drawing frame or other similar machine. A further object is to provide means for simultaneously moving a plurality of sliver cans in the manner above dened.

My invention further relates to certain arrangements and combinations of parts which will be hereinafter described and more particularly pointed out in the appended claims.

A preferred form of the invention is shown in the drawings, in which Fig. 1 is a side-elevation, partly in section, of a drawing frame embodying my improvements;

Fig. 2 is a plan view of the can-supporting table, looking in the direction of the arrow 2 in Fig. 1; f

Fig. 3 is a partial enlarged plan view, similar to Fig. 2 but with the table removed;

Fig. 4 is a partial bottom view of the cansupporting table;

Fig. 5 is a partial sectional front elevation, taken along the line 5-5 in Fig. 3;

Fig. 6 is a partial end elevation, taken along the line 6 6 in Fig. 3;

Figs. 7 and 8 are detail sectional elevations, taken along the lines 1-1 and 8-8 in Fig. 3; and

Fig. 9 is a diagrammatic plan view illustrating the coiling of the sliver.

Referring to Fig. 1, I have shown parts of a drawing frame which comprises a plurality of upper drawing rolls III and lower drawing lrolls II mounted in a drawing head I2 and adapted to receive sliver S from any suitable source of supply and to forward the sliver, after drafting by the drawing rolls, to a trumpet I4 which delivers the roving to calender rolls I5 and I8. The calender rolls discharge the sliver into an inclined passage I1 in a coiler head I8, which is provided with a ring gear I9 engaged by a driving pinion and continuously rotated thereby. As the sliver leaves the coiler head I8, it is deposited in a can C which is supported on a table 22 and which is preferably locatedthereon by guides or ribs 23. As shown in FIg. 2. the table 22 is designed to support four' cans which are spaced' to correspond with the spacing of four coiler heads in the drawing frame..

The parts thus far described, with the exception of the table 22, are or may be of any usual or commercial construction and in themselves form no part of my invention, which relates specifically to the mechanism for moving the table 22 in a horizontal plane.

This mechanism. as clearly shown in Figs. 3

to 8, comprises a pair of crank members in the form ofv worm gears 30 mounted on and rotated about fixed studs 3l and preferably provided with anti-friction bearings 32 (Fig. 6).- Each worm gear 30 is provided with an eccentrically mounted and freely rotatable bushing 33 which is equivalent to a crankpin. 'I'he gears 30 are engaged by worms 35 (Fig. 3) mounted onsl shaft 38 which is connected by bevel gears 31, a substantially upright shaft 33 and bevel gears 39 (Fig. l) to a drive shaft III, which shaft rotates in fixed speed relation to the driving pinions 20 for the' coiler heads I3.

The bushings 33 are so located in the worm gears 30 and the gears 30 are so meshed with the worms 35 that the bushings 33 rotate in angular unison and with the-distance between the two bushings maintained constant, as the bushings are mounted at the same'radial distances from the studs 3|. The table 22 is provided with downwardly extending pins or studs I3, adapted toslidably enter the bushings 33. 'I'he table 22 is also preferably provided with two additional pins or studs 43* adapted to slidably enter bushings SII mounted for free rotation at the free ends of crank members or arms 5I, pivoted on studs 52. 'Ihe bushings-50 are mounted at the same radial distances as the bushings 33, and the arms 5I are at all times free to swing or rotate in either direction.

When the studs 43 are inserted in the bushings 33 and the studs 43* in the bushings 5I), the table 22 is firmly supported near each corner thereof butin such manner that it may be' are free to move and to follow the same circular motion.

The table 22 thus receives a circular motion in a horizontal plane but without change in the orientation of the table with respect to the fixed structure of the drawing frame.

The can C is offset or eccentrically positioned with respect to the coller head i8, and the circular movement of the can C is at a much slower speed than the rotation of the coller head I8.

'I'he combination of these two motions causes the sliver S to be deposited in the can C in a series of superposed and substantially circular coils, each of which is angularly oil'set to a small extent from the preceding coil, as clearly shown in Fig. 9. With the coils thus disposed and with no twist imparted by the movement of the can, the sliver is depositedin perfect condition for withdrawal, whether single or duplex sliver is delivered to the sliver can.

By imparting movement to an entire table as a unit, rather than to each can separately, I am able to simplify the can-moving mechanism and to produce identical coiling results in each of a plurality of cans.

Having thus described my invention and the advantages thereof, Ido not wish to be limited to the details herein disclosed, otherwise than as set forth in the claims. but what I claim is:
